'TOOL-HOLDER SPECIFICATION forming part of Letters Patent. No. 323,727, dated August 4, 1885.

Appntauon mea M55-25, 1885. (No model.)

T a/Z whom it may concern:

Be it known that I, ANDREW J. PnAvnY, of Boston, (Somervilla) in thecounty of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Tool-Holders, of which the following is a full, olear,and exact description.

This invention relates to tool-holders which are composed ofa handle, made in parts, attached together, and adapted, the one to be turned upon the other without detachment, and of jaws arranged within the stationary part of said handle, which is chambered to receive them, and at one end entered into aslot at one end of the handle, and otherwise constructed, adapted, and connected to the turning part of the handle in a manner that the turning of the handle in one direction projects the jaws from the handle and opens them,and the turning of it in the other direction draws them into the handle and closes them, and thus the jaws, and through them the holder-handle, can be fastened to the tool which it is desired to use in the handle, and can be released therefrom, all as is well known.

The present invention relates to improvements in the detail construction of such toolholders, whereby many important advantages are obtained, as will hereinafter fully appear; and said improvements consist, iirst, in a hinged connection of the jaws to the carrier therefor, which carrier is adapted, as ordinary or otherwise, to be operated by the turning of the turning part ofthe holder-handle; second, in an adaptation of the holder-handle from end to end, so that, for instance, a rod may be inserted at either end and run through and made to project4 at the other end, and as so placed made fast by the tightening of the 40 jaws of the holder thereupon, or, again, so that with a tool held by the jaws at one end of the holder-handle the other end of said handlein the use ofthe holder can be placed upon a steadying-pin therefor as the tool carried by theholder is being worked, as may be desired; third, in a construction, adaptation, and attachment of the turning part of the holder-handle to the operating part of the j aws nal sections of a tool-holder of the present invention, illustrating in both the first and second part, and in Fig. l the third part, of

this invention, as just above stated. Fig. 3 is a similar View to Figsl and 2, illustrating, in addition to other features, a modification in the construction of the connection between the turning part of the holder-handle and the operating part for the jaws of the holderhandle. Figs. 4, 5, and 6 are cross-sections on lines 4 4, 5 5, and 6 6, respectively, Figsl and 2, and Fig-7 is an end view of the toolholder handle shown in Fig. 3, with the fastening-nut removed. Fig. Sis a cross-section on line 8 8, Fig. 3.

In the drawings, A represents the stationary and chambered part, and B is the turning part, of the handle of the present improved tool-holder. Within the chambered stationary part A are located the holding or gripping jaws C G, and these jaws, at one end of their holding and gripping ends D, project into or are in line with a diametrical slot, a, in the cap-piece b, covering one end of the stationary part A, and at their other ends theyare hung dle at the end thereof, to which the turning part is applied, and thence it passes through the axial bore or opening L of both of said handle parts and to the outside of the outer1V end of the turning part, at which end it receives a screw-threaded nut, M, attaching its said operating nut within the handle, as stated, and securing the two parts of the handle together, and in a manner allowing the turning part to be turned upon the stationary part and upon and over a shoulder, N, thereof. The operating screw-nut H of the turning part of the handle is interlocked therewith, and this interlock is shown as secured in Fig. l by making the nut at its exterior f of a square or ilatsided shape, fitting within a corresponding shape of the bore of the turning part B-in Fig. 3 in substantially a similar manner to that of Fig. l, but with this change, that the nut is made exteriorly ot' an oblong shape at its outer end, g, which is received by a corresponding-shaped hole, I), in a plate, Q, made attachablc and detachable, with its h oles h h and dowel-pins j j at the outer end of the turning part B of the handle, and in Fig. 2 by providing said operating screw-nut H with a male screw-thread and screwing the turnA ing part of the handle upon it. In all these instances the result is the saine-that is, the turning part ot' the handle is secured to the operating screw-nut, which is attached to the stationary part of the handle, and thus, with the turning and stationary part of the handle attached together by means of the fastening screw-nut and the jaw-carrier screwed into the operating screw-nut of the handle, the turning ot' the turning part of the handle in one and the proper direction will secure the projection of the holding or gripping ends of the jaws from the slotted end of the stationary part of the tool-handle, and in the other and opposite direction the drawing oit' said ends ot' thejaws into the handle, securing in the first instance, and in the usual and common operation of the back edge, 7c, of each jaw working against the end walls of the handle-slot c, and from the reaction of coiled springs Z, applied toand between each jaw and their common carrier or block E, an opening or movement of the jaws from each other, and, in the second instance, a closing or movement of the jaws toward each other. By this operation oi" the jaws, with the tool which they are to grip placed between them, said tool can be gripped, and thus made fast to the holder or released therefrom, as may be desired.

The jaws C C, in their opening and closing movement, swing upon the hinges eZ, making the connection between them and their common carrier or block E; and this hinge may be of various forms, two being shown-as, for instance, Fig. l, m is a pin attached to opposite sides of thejaw-carrier E, and n is a hole at one end or" each jaw. By these holes each jaw is set over upon its said pin, and thus the jaw is hinged to its carrier. Again, Fig. 2, g are lugs attached to opposite sides of the jaw-carrier, and q are notches at one end of each jaw, whichset over and thus tit thc jaws between the lugs of the carrier. Making the jaws separate from and hinging them to the jaws of their carrier or block E is a most eii'ective, advantageous, and prac- -tical construction, and renders either jaw at any time capable of detachment and removal i'or the insertion of another or for its repair; and, besides, it makes the jaw ready and quick in operation.

The jaw carrier or block E, its screw-threaded shank G, and the screw-nut M, fastening together the two parts ofthe handle, and also securing the jaw-operating screw-nut H within the handle, all have a passage, R, through them from end to end, and in an axial line with the grip of the jaws and of the tool-holder, and by this means, taken in connection with the usual opening between the jaws of the holder, the tool-holder is provided with a passage from end to end, and thus it is adapted for the insertion therein at either end of a rod of any suitable dimensions, and its extension through the handle, so as to project therefrom at either or both ends, and so that it may be then made fast to the tool.- holder by bringing its jaws to a grip thereon with a proper turning of the turning part ot' the handle. Again, this construction of the tool-holder with a passage through it enables the holder at its end having the fastening screw-nut to be placed upon a steadying-pin while the tool secured in it at its other end is being worked, as may be desired.

This invention, as to the attachment of the turning part of the handle to the stationary part, consists in the square or polygonal interlock between the operating screw-nut ol" the gripping-jaws and the turning part of the holder-handle, such as shownin Figs. l and 3.

Having thus described my invention, I claim,d

l. In a tool-holder, the turning and stationary parts A B of the handle, containing an operating screw-nut, H, in combination with separate gripping-jaws C, which are located in the stationary part ofthe handle, are hinged to a common carrier-block, E, screwing into said screw-nut, and at their gripping ends are adapted to be projected from and to be drawn into the handle, and thus to open and to close them, and all fastened together, substantially as described, for the purpose specified.

2. In a tool-holder, the turning and stationary parts A B of the handle, containing an operating screw-nut, H, and separate grip.- ping-jaws C, which are located in the stationary part of the handle, are carried by a coinmon carrier or block, E, screwing into said screw-nut, and at their gripping ends are adapted to be projected 'from and to be drawn into the handle, and thus to open and to close them, and all. fastened together, and provided with a passage, R, which leads through theni from end to end of the holder, substantially as described, for the purpose specified.

'3. In a tool-holder, the turning and stationary parts A B of the handle, containing an operating screw-nut, 1I, of external polygonal shape, fitting within a corresponding shape of the turning part of the handle, in combination with separate gripping jaws C, which are located in the stationary part of the handle, and are carried by a common carrier or block, E, screwing into said screwnut H, and at their gripping ends are adapted to be projected from and to be drawn into the handle, and thus to open and to close them, substantially as described, for the purpose speciiied.

4. In a tool-holdcr, the turning and stationary parts A B of the handle, containing an operating screw-nut, H, and separate grip- IOO screw-nut, and at their gripping ends are adapted to be projected from and to be drawn into the handle, and thus to open and to close them, and all fastened together, and provided with a passage, R, which leads through them from end to end of the holder, substantially as described, for the purpose speciiied.

5. In a tool-holder, the turning and stationary parts A B of the handle, containing an operating screw-nut, H, secured thereto by a screw-nut, M, and separate gripping-jaws C C, which are located in the stationary part of the handle, are carried by a common carrier or block, E, screwing into said screw-nut and at their gripping ends, and are adapted to be projected from and to be drawn into the handle, and thus to open and to close them, substantially as described, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
